SDK app signatures are correct for 2.7.0 - the last version for JWT app signatures was 2.6.0

your token:

{
  "typ":"JWT",
  "alg":"HS256"
}{
  "sdkKey":"cSM3aHO8Snaz...",
  "mn":"822998...",
  "role":0,
  "iat":"1662783815", // Saturday, 10 September 2022 04:23:35
  "exp":"1662813815", // Saturday, 10 September 2022 12:43:35
  "tokenExp":"1662813815" // Saturday, 10 September 2022 12:43:35
}

the value of exp/tokenExp is unusual, normaly it’s 2 hours after iat

zoom/meetingsdk-auth-endpoint-sample/blob/master/index.js

require('dotenv').config()
const express = require('express')
const bodyParser = require('body-parser')
const crypto = require('crypto')
const cors = require('cors')
const KJUR = require('jsrsasign')

const app = express()
const port = process.env.PORT || 4000

app.use(bodyParser.json(), cors())
app.options('*', cors())

app.post('/', (req, res) => {

  const iat = Math.round(new Date().getTime() / 1000) - 30;
  const exp = iat + 60 * 60 * 2

  const oHeader = { alg: 'HS256', typ: 'JWT' }

as first steps with zoom api, I would try the example app on Github (-> CDN client view)

there is a very good tutorial on youtube
